Connecting AC mains and ground to the Processor Unit
The Processor Unit is the computer that controls the SN90 system. It is a vital part of the
SN90 Purse Seine and Trawl Sonar. The SN90 Processor Unit must be connected to AC
mains, and it must be properly grounded.
Prerequisites
You must be equipped with a
standard set of tools. This tool set
must comprise the normal tools for
cable installation, such as different
screwdriver types, pliers, a cable
stripper and a soldering iron. Each
tool must be provided in various
sizes. We recommend that all tools
are demagnetized to protect your
equipment. Depending on the tasks
at hand, additional tools may be
required.
Context
The mains voltage for the SN90
Processor Unit is 115 or 230 VAC, and it will automatically sense the current supply
voltage. Two cables are used.
• AC mains cable: This cable is provided with the SN90 delivery.
• Ground cable: This cable must be provided by the installation shipyard.
Procedure
1
Locate the power input and the ground connectors on the rear side of your Processor
Unit.
2
Connect the AC mains cable from the Processor Unit to the bulkhead mains socket
or the Uninterruptible Power Supply (UPS).
A standard mains socket (identified with the arrow) is provided on the rear side
of the Processor Unit.
3
Connect the grounding cable from the nearest grounding point to the relevant
contact point or socket on the rear side of the Processor Unit.
A dedicated grounding point (identified with the arrow) is provided on the rear side
of the Processor Unit.
